Move E2E tests to Docker
Background / User story
Currently E2E tests require local setup to be run. Adding possibility to run them on Docker would:
- stabilise tests and allow to run them easily locally with reproducible results
- enable option to run them on CI
What to change
- Development: Adjust wdio.conf.js to enable running tests on Docker, provide Dockerfile and entrypoint to run tests on Docker image. Update README with steps how to run tests on docker.
Hints for testers
Try to run tests on Docker and see if it is possible.
Hints for translators
No need.
